Embolic Microspheres imhando yehydrogel microspheres inodzvanywa ine chimiro chakajairwa, pamusoro payo pakatsetseka, uye saizi yakaganhurirwa, iyo inoumbwa nekuda kwekuchinja kwemakemikari pazvinhu zvepolyvinyl alcohol (PVA). Embolic Microspheres ine macromer inobva kupolyvinyl alcohol (PVA), uye inopfava, haibvisike, uye inowanikwa muhukuru hwakasiyana. Mhinduro yekuchengetedza i0.9% sodium chloride solution. Mvura iri mu microsphere yakazara polymerized i91% ~ 94%. Microspheres inogona kutsungirira kudzvanywa kwe30%.
MaEmbolic Microspheres akagadzirirwa kushandiswa pakudzivirira kukuvara kwetsinga dzeropa (AVMs) uye bundu reropa, kusanganisira uterine fibroids. Nekuvharira ropa kusvika panzvimbo yaunoda, bundu kana kukuvara kwetsinga kunoshaya zvinovaka muviri uye kunoderedza saizi.
Munyaya ino, tichakuratidza matanho akadzama ekushandisa Embolic Microspheres.
Kugadzirira zvinhu
Zvinodiwa kugadzira sirinji imwe ye20ml, sirinji mbiri dze10ml, sirinji nhatu dze1ml kana 2ml, chigero chekuvhiya chine nzira nhatu, kapu isina utachiona, mishonga yechemotherapy, embolic microspheres, contrast media, nemvura yekubaya.
Danho 1: Kugadzirisa mishonga yechemotherapy
Shandisa chigero chekuvhiya kuvhura bhodhoro remushonga wechemotherapy wodurura mushonga wechemotherapy mukapu isina utachiona.
Rudzi uye chiyero chemishonga yekurapa nemakemikari zvinoenderana nezvinodiwa muchipatara.
Shandisa mvura yekubaya jekiseni kunyungudutsa mishonga yechemotherapy, uye huwandu hunokurudzirwa hunodarika 20mg/ml.
AMushure mekunge mushonga wekurapa nemakemikari wanyungudutswa zvizere, mushonga wekurapa nemakemikari wakaburitswa uchishandisa sirinji ye10ml.
Danho rechipiri: Kubviswa kwema microspheres embolic anotakura mishonga
Ma microspheres akaumbwa akazungunuswa zvizere, akaiswa mutsono yesirinji kuti aenzane nekumanikidzwa mubhodhoro,wobvisa mushonga nema microspheres kubva mubhodhoro re cillin uchishandisa sirinji ye20ml.
Rega sirinji imire kwemaminitsi maviri kusvika matatu, uye kana ma microspheres adzikama, supernatant inosundirwa kunze kwemushonga.
Danho rechitatu: Isa mishonga yeChemotherapeutic muEmbolic Microspheres
Shandisa nzira nhatu dzekubatanidza stopcock ne embolic microsphere ne syringe nemushonga we chemotherapy, nyatsoteerera kubatana kwacho zvakasimba uye gwara rekuyerera kweropa.
Sunda sirinji yemishonga yechemotherapy neruoko rumwe, wodhonza sirinji ine embolic microspheres neruoko rumwe. Pakupedzisira, mushonga wechemotherapy ne microsphere zvinosanganiswa musirinji ye20ml, zunza sirinji zvakanaka, woisiya kwemaminitsi makumi matatu, woizunza maminitsi mashanu ega ega panguva yekuenda kumwedzi.
Danho rechina: Wedzera midhiya yakasiyana-siyana
Mushure mekunge ma microspheres azadzwa nemishonga yekurapa makemikari kwemaminitsi makumi matatu, huwandu hwemushonga hwacho hwakaverengerwa.
Wedzera vhoriyamu ye contrast agent ka1-1.2 kupfuura vhoriyamu kuburikidza ne three way stopcock, zunza zvakanaka worega zvimire kwemaminitsi mashanu.
Danho rechishanu: Microspheres dzinoshandiswa muTACE process
Nekushandisa nzira nhatu dzekudzivirira, isa 1ml yema microspheres musirinji ye1ml.
Ma microspheres akaiswa mu microcatheter ne pulsed injection.
Zvinotungamira kutariswa:
Ndapota iva nechokwadi chekuti hapana utachiona hunoshanda.
Simbisa kuti mishonga yekurapa nemakemikari yakanyungudutswa zvachose usati waisa mishonga.
Kuwanda kwemishonga yechemotherapy kunokanganisa mhedzisiro yemushonga, kana huwandu hwacho hwakakwira, mwero wekunyudzwa kwemushonga unokurumidza, huwandu hwemushonga hunokurudzirwa hausi pasi pe20mg/ml.
Mvura isina utachiona yekubaiwa jekiseni kana 5% yeglucose ndiyo chete inofanira kushandiswa kunyungudutsa mishonga yechemotherapy.
Mwero wekunyungudika kwedoxorubicin mumvura isina utachiona pakubaiwa jekiseni waikurumidza zvishoma kupfuura kubaiwa glucose ne5%.
Jekiseni reglucose re5% rinonyungudutsa pirarubicin nekukurumidza zvishoma kupfuura mvura isina utachiona yekuisa jekiseni.
Kushandiswa kweioformol 350 senzira yekusiyanisa kwaive kwakanakira kuti ma microspheres amire.
Kana ikapinzwa mubundu kuburikidza ne microcatheter, inopinda mu pulse injection, iyo inobatsira zvikuru kumisa microsphere.
